Surely there's no refurbs yet. They can barely make news ones let alone process refurbs and whatever that involves. If a phone went back with a scuffed back you would assume that it would get a new rear case at the very least.

My scuffed ip5 had a model number of MD663ZP, my first and second replacement were ND663ZP. My first replacement had horrible battery life and the signal dropped occasionally for no reason, my second replacement was almost perfect except the battery still isn't as good as my original one.
